The edge of the center circle will be build out line if no other line is visible

Furthest build-out line is new offside line (only called if obvious)

Opponents must retreat behind build out line whenever GK has possession

On goal-kick, opponents may not break build-out line until the ball leaves the penalty area

GK is not allowed to punt or drop-kick the ball - must pass, throw, or roll the ball into play

Substitutions: Can be made by either team at any stoppage with the permission of the referee - players must be ready at the half-line.
